SIDE SPRING.

SPECIFICATION forming part of Letters Patent No. 283,052, datedAugust14, 1883.

Application flied November 24, 1882. (No model.)

To all whom it may concern Be it known that I, CHARLES R. WILSON, ofDetroit, county of Wayne, State of Michigan, have invented anew anduseful Improvement in Springs for Side-Bar Vehicles; and I declare thefollowing to be a full, clear, and exact description of thesame, such aswill e11- able others skilled in the art to which it pertains to makeand. use it, reference being had to the accompanying drawings, whichform a part of this specification.

My invention consists in the combinations of devices and applianceshereinafter specified;- and more particularly pointed out in the claim;V

Inthe drawings, Figure 1 is a plan view, Fig. 2 a side elevation, andFig. 3 aperspective View, illustrating my invention.

It is the object of my invention to produce and combine with aside-barvehicle a spring which shall be composed of the two followingelements: Alower section extending across the sessed by the ordinarydouble spring, in which the upper and lower sections areparallel witheach other, and the further advantage of a greater length of spring inthe upper section, between the middle and extremity of the spring, andwithout projecting the end of the upper section beyond the sides of thebuggybody. y z

In carrying outmy invei'ition A represents the side bars of an ordinaryside-bar buggy;

B, the buggy-body; G, the upper, and O the lower, section of my improvedspring. 0

represents the end portions of the upper secti on, which are turned,either forward or backward, beneath thebuggy-body in a directionparallel to its length. I prefer to slope these longitudinal portions 0so that their extremithe buggy-body through a corresponding length,andthus render the spring stifl'er.

If the spring is at the outset designed for heavy loads, the portions (3maybe made quite short, and might be so much shortened that the,

upper section would possess only the elasticity due toits divergingportion and the torsional elasticity of the. material at the base of thelongitudinal part 0.

I do not limit myself to any particular method of uniting the twosections 0 and 0. They ties only shall come up beneath the buggybody,and to secure these extremities firmly.

may be made with the lower section bent upward and the upper sectionbent downward .along the middle, and fastened by a bolt or suitableclips at the middle point; or both sections may be bowed upward atthemiddle point, or both bowed downward at the middle point, and securedin any suitable manner,

so as to lap'upon and re-enforce each other as i the load is increased,or the sections may be separated along the middle part by one or moreblocks, thus preventing them from so lapping upon each other; and Iwould have it understood that in constructing my spring any of theforegoing constructions are contemplated. So, also, Ido not limit myselfstrictly to aconstruction in which the upper section, 0, is brought outto the sides over and parallel to the lower section, for it may bestarted outinthat direction and then brought around, by an easy curve ofgreater or less radius until the extremities point to the front or rear,while the middle rests upon the lower leaf.

I am aware that it is not new to construct a spring for a vehicle-bodyof two flexion members or springs arranged one above the other andconnected at their centers, the outer ends of the upper member beingarranged parallel IOC with the ends of thelower member and securedcenter of said upper spring, and sidebars or to the body of the vehicle,and the ends of the other support, as and for the purpose set forth. 10lower member being attached to the side bars In testimony whereof I signthis specificaor other support. tion in the presence of two Witnesses.

5 What I claim is- CHARLES R. WILSON.

The combination of the upper transverse Witnesses: spring, havinglongitudinaHy-turned end por- N. S. WRIGHT, tions, with the bottomspring, secured to the WILLIAM F. FORD.
